OWLS (OverWhelmingly Large Simulations) project consists of a large suite of cosmological, smoothed particle hydrodynamics (SPH) simulations with varying box sizes and resolutions. It was made possible by the temporary availability of the supercomputer that serves as the correlator for the Low Frequency Array (LOFAR) telescope, and aims to use the potential of simulations to gain insight into the physics that determines the formation of galaxies and the evolution of the intergalactic medium
The real power of the project stems, however, not from the size of the simulations, but from
the fact that they are repeated many (more than 50) times, each time varying a subgrid
prescription, most of which were newly developed
for this project.
The initial paper for “The OWLS Project” has been published as Schaye et al. 2010. For more information please contact Joop Schaye.
